Power line carrier wave meter reading control system for gas meter

Abstract

The invention relates to a power line carrier wave meter reading control system for a gas meter, which is characterized in that a power line carrier wave communication collector is connected nearby the gas meter through a signal line and also connected with a data concentration processor through a power line; and the data concentration processor uploads signals to a management computer. In the invention, the data transmission is carried out through the power line to form the power line carrier wave meter reading and control system for the gas meter. Because of entering thousands of households and being a huge power network system, the power line not only is used for electric energy transmission, but also has the communication function to an embedded carrier wave and is improved into a communication network, and the prior-period investment and later-period maintenance cost thereof are cheap. A whole network is formed only through adding a carrier wave device during the construction, thereby having large expandability and extensibility.

Description

technical field [0001] The invention relates to a gas meter power line carrier wave meter reading control system for realizing remote automatic meter reading and remote automatic control by using the existing power line network through carrier communication. Background technique [0002] In the current market application, there are mechanical gas meters installed in the early days, and the meter readers bring paper and pens to copy them manually. This method not only requires a lot of work, but the copying is not timely, and the data is prone to mis-copying and missing copying. If the resident is not at home, it will cause the phenomenon that the copy cannot be returned for a long time; some gas meters with infrared devices are installed, and the meter reader only needs to bring a matching handheld, which is similar in shape to the walkie-talkie.

Problems solved by technology

[0002] In the current market application, there are mechanical gas meters installed in the early days, and the meter readers bring paper and pens to copy them manually. This method not only requires a lot of work, but the copying is not timely, and the data is prone to mis-copying and missing copying.

If the resident is not at home, it will cause the phenomenon that the copy cannot be returned for a long time; some gas meters with infrared devices are installed, and the meter reader only needs to bring a matching handheld, which is similar in shape to the walkie-talkie. Missed copying, but the phenomenon of heavy workload, untimely copying, and long-term copying still exists

Because it is still a single meter, it does not constitute a network system; there is also a wireless copying system installed, which can be copied without entering the house. However, due to the strict management of wireless communication by the Radio Management Committee, the power allocated to civilian use is relatively small, and the frequency band is inferior. However, the current urban buildings are all steel frame structures. Natural gas meters are generally installed indoors, and the shielding is relatively serious. Most of them cannot be read, and it is difficult to form a wireless remote meter reading system; It must be pre-embedded, the material used is the same as that of telecommunication cables, the cost is high, and the amount of maintenance in the later period is large, especially when the user is decorating, it is easy to cause damage to it

It is even more impossible to use the old buildings that have already moved in. When laying the dedicated line, because the original building has to be smashed into the wall and holes are drilled, there is still a one-time laying of the dedicated line. If you want to add new users, you have to lay it again. Scalability and extensibility, and the commissioning time is long, so the dedicated line gas meter reading system cannot be used on a large scale
